About this game

Ever wanted to be the villain? To build a lair? Hire henchmen? Fight superheroes? Concoct dastardly plans? Raid a city? Or… take over the world?

No? What, really? Sure you do!

Idle Mastermind, from the makers of Idle Apocalypse, is the best supervillain simulator of 2020! Play as three supervillains. The techy but tiny: Dr DOS. The gangster crime boss: Yara. Or the unpredictable: LOL. Each has their own evil grand plan.

Build a lair to run your empire from. Hire a bunch of evil henchmen to do your bidding. Raid the city above to gain precious resources. Unlock new research and skills to improve your criminal, idle empire.

When you’re ready, execute your evil plan and bring about the apocalypse!

Play as 3 distinct villains, each with:
+ A unique lair with special floors and henchmen.
+ Different strategies, skills and stories.
+ Unique resource management styles.

Build your dream lair:
+ 30 unique floors.
+ Floors that will generate resources while offline.
+ Special floors with unique gameplay elements.

Hire an army of evil thugs:
+ 20+ henchmen.
+ Different classes, abilities.
+ Unique resource management gameplay.

On top of that it has all the humour and inane chatter of a Grumpy Rhino game. The makers of Idle Apocalypse.

Lovers of simulation games and incremental clickers won’t be able to put down this dastardly, near criminal RPG.

If you've played their other games, you know what to expect. Pay to win, pay to remove irritants, pay to remove walls not meant to be overcome. Biggest gripes are the fact that the events which are necessary for forward progression can not be overcome without using the in-game currency (to "win" enough to get the Evil Eye endorsement) and real money (to win all the prizes). I need those gems to buy useful henchmen and unlock the next supervillain. But oh you can pay $25 to unlock that too.

Pretty fun game, much like all the others made by this dev team. Always liked the little events and such, and how removing ads removes them completely. Especially happy about the cooldown on events as opposed to the replay tokens in idle apocalypse. And you can potentially play to completion without spending anything, because the login rewards are pretty good. Takes a long time to beat even with money, so you get plenty out of the game.

Overall a solid gameplay loop without the ads being too intrusive. You choose when to view ads, nothing is forced on you as the player. The rewards for a 30 second ad are pretty decent however. The idleness works well and the active gameplay parts are fun. There is the option to deactivate ads for 9.99 forever, but that honestly feels too steep. Would have insta bought that if it was at 2.99-3.99. possibly 5.99
